Gear Box for Tracked Jeep

I am rebuilding a 1943 Canadian Tracked Jeep known as the TJ2. The engine is standard jeep, but the gearbox is missing. It was produced by Marmon Herrington & was also fitted in a 1940's van called the DELIVRALL. See photo. A gear box in any condition would help or any information regarding same.
